HVAC Company Serving Richmond Heights, MO

Most of Richmond Heights was built before World War II. Arts and Crafts bungalows in the Hampton Park Historic District, pre-war brick two-stories along Bennett Avenue, apartment buildings from the early 1900s, some listed on the National Register of Historic Places. That construction era shapes what HVAC work looks like here: older ductwork, radiator systems without central air, limited equipment access, and historic interiors that cannot simply be opened up and rerun.

That kind of work calls for an HVAC company that knows how to look at the whole property, not just the equipment. Here is what Martin-Jetco Heating and Air Conditioning brings to every Richmond Heights service call:

• Family-owned since 1964. Martin-Jetco Heating and Air Conditioning has been serving St. Louis County homeowners for decades, including through the eras when many Richmond Heights homes were being updated and expanded.
• Licensed, NATE-certified technicians on every visit. NATE is the industry's leading independent credential, verified by examination, not just internal training.
• Full system range. Repair, replacement, and installation for furnaces, air conditioners, heat pumps, boilers, and ductless systems.
• Clear pricing before any work begins. No open-ended commitments. The technician explains what is wrong and what it costs before anything is authorized.
• Emergency service at any hour. Evenings, weekends, and holidays included.

Do not let old ductwork, poor airflow, or aging equipment decide comfort for you. Call (636) 205-1631 or message us online to get practical HVAC answers.

How Much Does a New HVAC System Cost in Richmond Heights?

Most residential replacements in Richmond Heights fall into two categories:

• AC Replacement with evaporator coil: approximately $5,500 to $9,200
• Complete HVAC system (furnace and AC): approximately $8,450 to $22,990 or more

What affects the final number:

• Square footage and the tonnage the system needs to cover
• Ductwork condition, including whether it needs sealing, resizing, or full replacement
• Standard versus high-efficiency variable-speed equipment
• Zoning systems for homes with multiple levels or distinct temperature zones
• Electrical or code updates required before new equipment can be installed
• Indoor air quality components added to the project
• Access challenges in pre-war construction with plaster walls, narrow chases, or finished historic interiors

For Richmond Heights homeowners, an AC replacement with evaporator coil typically runs approximately $5,500 to $9,200, while a complete HVAC replacement ranges from $8,450 to $22,990 or more. In a city where a significant share of homes were built before 1940, the condition of the existing ductwork is often the single biggest variable in the estimate. 

An in-home evaluation is the only way to account for all of it accurately. Martin-Jetco Heating and Air Conditioning can inspect your equipment, ductwork, access points, and comfort concerns, then walk you through clear replacement options for your Richmond Heights property.

Why Older Richmond Heights Homes Present Distinct HVAC Challenges

Richmond Heights has a deep stock of older homes and buildings, including two designated historic districts, many pre-1940 properties, brick bungalows, Arts and Crafts two-stories, and pre-war apartment buildings. That history gives the city its character, but it also affects how heating and cooling systems are installed, repaired, and replaced.

In many homes, the HVAC system has been updated in pieces over several decades. A house may have original construction, older ductwork, newer equipment, radiator heat, added central air, or electrical updates from different eras all working together. That is why HVAC work here often requires a closer look at the whole property, not just the unit that needs service.

Here are the issues Martin-Jetco Heating and Air Conditioning sees most often:

• No central air in homes built around radiators. Many of Richmond Heights's oldest single-family homes were originally heated by boilers and radiators with no ductwork whatsoever. Adding modern cooling to these properties means either running new ducts through finished historic interiors or installing ductless mini-splits that deliver independent room-by-room cooling without disturbing original plasterwork.
• Ductwork that has never been evaluated. Homes that had central air added in the 1970s or 1980s often have duct systems that were pieced together at the time and never assessed since. You’ll notice signs such as uneven airflow, rooms that run noticeably warmer or cooler than the rest of the house, and new equipment that underperforms against its efficiency rating.
• Pre-war apartment buildings with complex configurations. Richmond Heights has a dense concentration of multi-family housing. These properties involve shared infrastructure, limited mechanical access, and tenant logistics that single-family jobs do not.
• Homes where renovation and original construction are mixed. A home that has been updated over the decades may have a mix of original ductwork, newer equipment, and electrical infrastructure from different eras. A technician has to look at all of it together before making a recommendation.

Ways to Lower the Cost of Replacement

A new HVAC system is a major investment, but the final number may be reduced by financing, rebates, credits, or current offers. During your estimate, Martin-Jetco Heating and Air Conditioning reviews what may apply to your project, including:

• Financing for qualifying projects, which can spread the cost into manageable monthly payments 
• Utility rebates processed on your behalf at the time of installation 
• Federal energy-efficiency tax credits for qualifying heat pumps, high-efficiency furnaces, and AC systems 
• Seasonal promotions available at the time of your estimate 

You see the equipment cost, payment options, rebates, credits, and promotions in one place, so you can compare the real cost before making a decision.

Get Consistent Care with the Home Comfort Agreement

Martin-Jetco Heating and Air Conditioning's Home Comfort Agreement keeps your system on a scheduled inspection cycle, with visits timed before each peak season rather than after a problem reveals itself.

• Seasonal visits before cooling and heating demand peaks each year
• A thorough safety and performance inspection at every visit
• 20% savings on parts and labor for any repair between scheduled visits
• Priority scheduling when an unplanned service call is needed
• No premium for calls made outside regular business hours

Frequently Asked Questions

Can you add air conditioning to a home that has radiator heat and no ductwork? 

It depends on the property, but yes. In older Richmond Heights neighborhoods around Hampton Park and Bennett Avenue, the best option usually comes down to how much of the home can reasonably be disturbed. If preserving plaster ceilings, original woodwork, or historic finishes is a priority, ductless mini-splits can add room-by-room cooling without running new ducts. If the layout allows ductwork to be routed through an attic, closets, or other less finished spaces, conventional central air may be a practical option. An in-home evaluation helps determine which approach fits the property.

My furnace runs but the heat is not reaching the house. What is going on?

If the system is running but the air coming through the vents feels cold or room temperature, the burners are likely not firing even though the blower is on. This can happen for several reasons:

• The heat exchanger overheated from restricted airflow, typically caused by a clogged filter, and the safety limit switch shut the burners off while the fan kept running
• The ignitor is failing to complete its sequence, meaning the gas never lights
• The flame sensor has enough buildup on it that it cannot detect a flame even when one is briefly present
• The gas supply to the unit is interrupted or the pressure is low
• A control board fault is preventing the thermostat signal from reaching the combustion side of the system

Because these issues involve gas, ignition, heat, and built-in safety controls, do not keep resetting the furnace or trying to force it to run. Call (636) 205-1631 so a licensed technician can diagnose and issue and inspect if the equipment is safe to operate.

Do you service boilers in Richmond Heights?

Yes. Boiler work comes up regularly throughout the older parts of the city. The service covers diagnostics and repairs, seasonal maintenance to keep the system running efficiently before heating season, and full boiler replacements when the existing unit is no longer worth maintaining. If converting from boiler heat to a forced-air system is something you are considering, we can walk you through what that would involve for your specific property.

My AC runs constantly but the house never fully cools down. What should I check?

Start with the filter, since a dirty or clogged filter can restrict airflow enough to keep the system from cooling properly. Other common causes include low refrigerant from a leak, a dirty outdoor condenser coil, or ductwork problems that let conditioned air escape before it reaches the rooms that need it. In older homes, especially where ductwork was added after the home was built, undersized or leaky runs can also play a role. A technician should check refrigerant charge, airflow, the condenser, and the duct system before recommending an AC repair or a more involved fix.

Are heat pumps practical for my home? 

Yes, if the ductwork is in good condition and can move air properly. Modern heat pumps handle Missouri winters much better than older models, and they can provide both heating and cooling in one system. In Richmond Heights, the main question is whether the home’s ductwork was designed, added, or balanced well enough for the system to perform efficiently. For homes without ducts, a ductless mini-split heat pump may be worth comparing against other options.

How often should HVAC systems in Richmond Heights homes be serviced? 

Most Richmond Heights homes should have HVAC maintenance twice a year: once in spring before AC season and once in fall before heating season. In older homes, especially those with older ductwork, radiator heat, retrofitted central air, or mixed-age equipment, seasonal service is especially important because small airflow, safety, or efficiency issues can be easier to catch before peak weather hits. Homeowners should also check filters regularly between visits, since clogged filters can restrict airflow and strain the system.
